Abstract

The invention relates to an inert gas protection platform for a micro-forging-rolling composite additive manufacturing system, which comprises a platform whole body, the platform whole body comprises a printing substrate, a gas transmission device and a heating substrate, and the peripheries of the printing substrate and the heating substrate are provided with an integrated frame and an annular gas outlet groove; a plurality of inert gas inlets communicated with the annular gas outlet groove are formed in one side face of the integrated frame, and the gas transmission device is connected with each inert gas inlet through a gas distribution pipe. Inert gas is continuously and uniformly output from the bottom of the whole platform to the annular gas outlet groove in the whole platform through the gas distribution pipes, so that air above a printing substrate is discharged out of the whole platform, powder is prevented from being oxidized and denatured in the air, efficient operation of powder laying printing work can be ensured. Therefore, the production efficiency is improved, and the product quality is finally improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an inert gas protection platform for a micro-forging and rolling composite additive manufacturing system. Background technique [0002] The powder feeding process of the traditional coaxial powder feeding type additive manufacturing is that the powder feeder continuously inputs the metal 3D printing powder material. During the process of melting the powder, it is easily oxidized by the oxygen in the external environment, which will eventually affect the forming quality. , using the laser head inert gas shielding gas method, that is, there will be a shielding gas nozzle in the laser head part of the cladding equipment, so that the effect of isolating the air can be realized by continuously spraying out the shielding gas during the cladding process. The metal powder is heated and melted by contact with the laser, and then solidifies rapidly, and forms a metallurgical...
